Nice question, reader Ian. I’m sure there aren’t any in Australia. Up until recently there weren’t many outside of Pennsylvania and the New England region of the US. I’d never seen or heard of one until I started working at suburban Chicago bakery around ten years ago. Then, whoopie pies were considered quite exotic things in the Midwest. These days, however, just about every serious baker and/or sweet eater in the US has at least heard of a whoopie pie, as they’ve become quite the trendy item the last 5 years or so.
Classically a whoopie pie is a sort of sweet sandwich made with a chocolate cake “bun” and a filling of vanilla frosting. Quite simple things, really, but Lord let me tell you, they’re good. I haven’t tried any of the more exotic versions that are around nowadays, as I’m a simple country fellow at heart and I both loathe and fear the unknown. But I’m told some of the variations that are out there — which range from pumpkin to banana, lemon, peanut butter, strawberry, red velvet, gingerbread and zucchini — can be quite good. Me, I’ll stick with the basics, cool?
